Similar problem, but mine is after conversation has been going on for a few minutes, then all of a sudden they can't hear me but I can hear them fine.

Also, phone now cuts out about every 10-15 words. Pretty sure nothing spilled into microphone.Similar problem, but mine is after conversation has been going on for a few minutes, then all of a sudden they can't hear me but I can hear them fine.

I can both call out and receive calls but, the other person cannot hear me. The first handset did this within 6 mos of purchase. We have used the remaining handset for 2 years and it finally did the same thing. I came on to "FixYa" and found the solution given to cescoffy. I proceeded with the fix on both handsets....Woo Hoo! We now have 2 handsets again that work perfectly. Thanks.

For 2+ years, I've had a cordless DCT646-2 sitting in my kitchen that was only good for just checking my voicemail since the microphone appeared not to work. I followed maied's instructions (except I left out the cloth dot at the end), and I now have a fully functioning phone in my kitchen once again.

With that cloth dot and the sticky residue, I don't even want to think about what kind of microbial action is going on in my other phones.

Thank you, maied, for your solution! It worked like a charm!

I had the same problem with two of these handsets.
I am not certain of the cause, but based on the fix, I believe water got into the microphone holes and perhaps mixed with a water soluble glue that stuck the felt cover to the microphone.
I fixed the problem by removing the battery, opening up the phone (slide the battery cover off and removed the 4 screws) and snapped open the plastic encasement. Then I remove the two screws toward the top (toward antenna) of the circuit board.
This gave me access to the microphone which is on the underside of the circuit board (very bottom of the phone, below and on the opposite side of the plastic jumper for the battery) which had a thin black felt cover covered in a sticky residue that was covering the microphone diaphragm. I removed the felt and then used a cotton swab with rubbing alcohol to remove the residue from the diaphgragm. I used compressed dry air to remove any dust from the diaphgram.
With the 2 screws, I secured the circuit board back in, snapped the plastic case back together. Then I finished off with putting 4 screws in the case and putting the battery in.
Now other parties can hear me just like they used to when the phone was working.

Thanks Maied for your post. Very big help! I used to have 4 of these phones where the mouthpiece on one seemed to quit working. Thinking it was an electronic issue, I tossed it, and now I am down to 3 phones. Then 1 of the remaining 3 had the same issue, and I thought, "Oh no, not again!! I really like these phones!" I didn't want to toss another one and end up with 2, so I researched online and found this post. My 3rd phone is saved from the trash thanks to you. I'm now kicking myself for not thinking to research the internet sooner! Oh well. Glad to still have three phones and not two. Thanks again!Thanks Maied for your post. Very big help!

Re: I can hear caller but they can't hear me

That totally fixed it. thanks maied for your pioneering efforts! it seems that that moist sticky stuff, which must be glue is rather runny and it's all over the place, under the rubber keypad. can only imagine the toxic nature of it.

Re: I can hear caller but they can't hear me

Maied was right, i did exactly what he said and it worked. I however, removed the diaphragm and cleaned the speaker with alcohol. I was about to throw away my four phones and purchase something else. All of my phones are working fantastically. Thanks

Did you drop your phone? It seems that your phone's caller speaker is damaged thats why you can't hear the caller. If this is the problem then the only solution is to replace the speaker. Hardware is not covered under warranty, but you should check with the warranty provider. Otherwise, take it to any mobile repair shop and ask them to change the speaker.

not sure if its the same problem but i had that with a different model and was told when i placed the charger in the phone it moved the mic slightly and thats why it was not working as it should i used my hands free every time i made a call mine was so bad ..it was a manufacture fault so i was lucky and had the phone changed free !!! hope this helps

You've got an IP issue somewhere in your setup. It sounds like the call is being lost and then the phone is querying the DNS server to find out where it should be looking for the call.
Do you have a VOIP server name or it's IP address in the setup? Are you using DHCP or manually assigning IP addresses? If the VOIP server is not on a static IP, I would fix that first.
Post back here the answers and we can look at it further.
